Letters Patent No. 73,837, dated January 28, 1868.

IMPROVED BENDINGMAGEINE.

To ALL WI-IoM IT MAY CQNCEEN:

ing drawings, forming part. of this specication, in which- Figure l is eside elevation..

Figure 2 u top View.

Figure 3 is an end view.

This invention combines a new arrangement of gear, by which great poweris exerted at the points which require it, and a new method of'adjusting the central relier, by which the tires can -be moreeasilyapplied and removed thun in machines used heretofore.

In the drawings, A A are corrugated ironrollers, bearing in a fixed ironframe, B, provided with 1ugs,6 6, for the purpose, and` supported by nwooden frame', F. To one end of these rollers are xed two'largegcarwheels, a a; of'equ'al size, rot-ated in the same direction by asmall spur-wheel, c, between them. The shaft that beurs the spur-wheel cbears also a. large spur-wheel, C, which is rotated by another smallspur-wheel, c', fixed to n short shaft, C', driven by power applied atthe crank C.` The whole gearing constitutes an arrangement by which thetwo rollers are driven with equal velocity, and ivith immense power.Between the rollers A A is a vertical sliding frame, D, working in gainsor notches in the sides-of the iron frame B, and capable of beingadjusted at any required elevation by a screw, S, beneath the frame F.The frame D at its upper extremity bears the middle roller R, n, smoothroller Working in the same direction as the rollers A A', und exactlyhalt' way between them.' The tire, in the shape of, a straight ironb,ar, is reduced to the proper shape for fixing upon the Wheel, byinserting it between the lower rollers A A and upper one R, and turningthe crunk C" until it has been subjected throughout its whole lengthstothe action of the three rollers.

In order to facilitate the insertion of' the iron ber between therollers, as described, andits removal from them, we make the outer sideof the vertical frame D of two parts, one port, d, immovably iixed tothe bottom cross-bar, and the other part,cZ, hinged to the top of thelower piece d, so as to swing outward or inward upon the hinge it. Thehinged piece d carries one of the bearings, r, ofthe upper or middleroller. The otherbearing ofv the middle roller is in En uprightstandard, M, on the opposite side of' the iron frame B. A link, L,extends across above the roller, connecting the upper' ends of the twouprights d M which support the roller, being attached to'one oftbem by ahinge, Z, and dropping over a. projection, e, upon the other, so as toconne them in the position shown in figure.

When it is necessary to insert the'tires between the rollers forbending, We lift the link L 01T of the projection e, swing the sidepiece d outward till the journal of the roller R escapes from its box,raise the end of the middle roller, and insert the bar in its place. Theparts are then to be replaced and the tire bent, after which it mayberemoved in the same nl anner.

Having thus'described our invention, vf'halt we claim as new, and desireto secure by Letters Patent, is

The combination of the roller VR with the jointed frame which supportsit, constructed substantially as described.
